The spaces between sections of myelin on an axon are termed the:
A)nodes of Ranvier.
B)sodium-potassium pumps.
C)ion channels.
D)synaptic junctions.

Question

Quizplus · Accepted Answer

The spaces between sections of myelin on an axon are called nodes of Ranvier. These are important for the conduction of nerve impulses and allow for saltatory conduction, where the nerve impulse jumps from one node to the next, increasing the speed of conduction. Sodium-potassium pumps, ion channels, and synaptic junctions are all important for the functioning of nerves, but they are not located specifically in the spaces between sections of myelin.
